I plan to transfer in the spring after my first semester at college, and I read that when transferring getting a recommendation from a high school teacher is unacceptable. Does this still apply if I am barely out of high school? I just started my first semester and my professors don’t know me and I feel that asking for a recommendation from any of them would be useless.
Yes. You will need letters from your current professors. So start haunting their office hours, get to know them a bit, and ask them about this.
